Interesting, this surly will provoke a move back to the more traditional ink sources as used in the pre-industial age and possibly futher back – early medievil age and futher still. I think I read somewhere that there are inks and dyes that are of natural composition that are actually far better than the modern chemical builds, but as far as I can see they aren’t commercially viable due to the exsessive costs involved in ‘farming’ them as well gaining shipping clearances. But I could be wrong.
